Application filed June 22, 1905. Serial No. 266,495.

To a, whom it may concern:

Be it known that I, HENRY DEL JACOBSON, a citizen of the United States, residing at Atlantic, in the county of Cass and State of Iowa, have invented certain new and useful Improvements in Perforating-Machines, of which the following is a specification.

This machine is designed to perforate a rectangular sheet or superposed sheets of paper along a line parallel to and at a predetermined distance from one edge.

The machine comprises a support or table to receive the sheet, having a longitudinal recess faced with steel strips to receive the perforator, a straight guide-rod mounted at one side, a slide surrounding the guide-rod and having a lateral arm, and a perforator revolubly supported on the end of the arm consisting of a thin toothed disk of hardened steel clamped between disks of cast-iron. The table is provided with a fixed gage for the lower edge of the paper sheet and with a transversely-adjustable gage for the side of the sheet to determine the position of the line of perforations.

Referring to the accompanying drawing, the figure is a perspective view of the complete machine.

The machine comprises a flat rectangular support or table 1, near the middle of which and parallel to one edge is a straight narrow slot 2, faced at each side by steel strips 3. A straight round guide-rod 4, having an adjustable stop-collar 16, is mounted above the table,

near one edge, being supported at its ends by pieces 5. Surrounding the guide rod is a sliding sleeve 6, which has a lateral arm 7 extending across the table to the recess 2. Upon the end of this arm is journaled the pere forator 8, which consists of a thin toothed disk 9, of hardened steel, clamped between cast-iron disks 10. A two-part fixed gage 11 is secured to the table near its forward edge. Another gage 12 is arranged to move to and from the perforator in a transverse slot 13, being clamped in adjusted position by a bolt and wing-nut 14. A spring-finger 15 to hold the lower edge of the paper is secured to the table at the end of the recess 2.

In using the machine the sheet of paper is placed on the table with its edges in contact with the gages 11 12, the arm 7 and perforator 8 being raised or drawn backward. The oper ator then grasps the arm 7 forces the teeth of the perforator into the paper, and pushes it to the rear edge of the table, the toothed disk rotating on the end of the arm and cutting a line of perforations in the paper parallel to its edge and at a distance therefrom predetermined by the position of the gage 12.

I claim- 1. A- perforating-machine, comprising a support having a longitudinal recess and a guide, a slide having a lateral arm, and a toothed disk revolubly supported on the end of said arm in alinement with said recess, as set forth.

2. A perforating-machine, comprising a support having a longitudinal recess and a guide, a slide having a lateral arm, a toothed disk revolubly supported on the end of said arm in alinement with said recess, and a transversely-adjustable gage, as set forth.

3. A perforatingmachine, comprising a support having a longitudinal recess, a guiderod mounted above said support, a slide surrounding said rod and having a lateral arm, a perforator journaled on the end of said arm, consisting of a thin toothed disk and clamping members, a fixed gage, and a transverselyadjustable gage, as set forth.

4. A perforatingmachine, comprising a support, a guide having an adjustable stop, a slide having a lateral arm, and a perforator at the end of said arm, as set forth.

5. A perforating machine, comprising a support having a longitudinal recess, a guiderod mounted above said support, an adjustable stop-collar on said rod, a slide surrounding said rod and having a lateral arm, a perforator journaled on the end of said arm, consisting of a thin toothed disk and clamping members, a fixed gage, and a transversely-adjustable gage, as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

HENRY DEL JACOBSON.
